On the PCB board, a kind of special glue is put on the position where the chip needs to be pasted. After curing, it goes through the oven. The coating is carried out automatically according to the program. The coating machine is mainly used for spraying, coating and dripping three proofing paint, UV glue and other liquids to the precise position of each product. It can be used to draw lines, circle or arc.
Conductive adhesive is a kind of adhesive with certain conductivity after curing or drying. It is usually composed of matrix resin and conductive filler, i.e. conductive particles. The conductive particles are combined together through the bonding effect of the matrix resin to form a conductive path and realize the conductive connection of the bonded materials. Because the matrix resin of conductive adhesive is a kind of adhesive, it can choose the appropriate curing temperature for bonding. At the same time, due to the rapid development of miniaturization and miniaturization of electronic components and high density and high integration of printed circuit board, conductive adhesive can be made into paste to achieve high linear resolution. Moreover, the process of conductive adhesive is simple, easy to operate, and can improve the production efficiency. Therefore, conductive adhesive is an ideal choice to replace lead tin welding and realize conductive connection.
Printed circuit board (PCB), also known as printed circuit board, is the provider of electrical connection of electronic components. Its development has been more than 100 years; its design is mainly layout design; the main advantage of using circuit board is to greatly reduce wiring and assembly errors, improve the level of automation and production labor rate.
Fingerprint module is the core component of fingerprint lock, which is installed on devices such as fingerprint access control or hard disk to complete fingerprint collection and fingerprint identification. Fingerprint module is mainly composed of fingerprint acquisition module, fingerprint identification module and extended function module (such as lock driver module).
Mobile phone TP is an inductive liquid crystal display device which can receive input signals such as contacts. When touching the graphic buttons on the screen, the tactile feedback system on the screen can drive various connecting devices according to the pre programmed program, which can replace the mechanical button panel, and make dynamic video and audio effects by LCD display.
The performance of mobile phone digital camera in the development stage should also be in the primary stage, only a few mobile phone cameras have optical zoom function. However, I believe that with the development of mobile phone digital camera function, most mobile phones will have digital zoom function. In addition, the functions of mobile phone digital camera mainly include still image shooting, continuous shooting, short film shooting, lens rotation, automatic white balance, built-in flash, etc. The shooting function of mobile phone is directly related to its screen material, screen resolution, camera pixel and camera material.
FPC flexible circuit board is a kind of flexible printed circuit board with high reliability and high quality, which is made of polyimide or polyester film. It has the characteristics of high density, light weight, thin thickness and good bending property.
